The present invention relates to a con.- struction by which the cylinders may be relieved entirely from the transmission of b means of the sta -bolts being carried up through the cylin er covers, which are already of heavy construction, because they have to resist the large ex lesion pressures, while the cylinder .7 to stand this pressure onl for portion ofits top part, and there- 1- 1 t as far as e 'is concerned.

As the Stay-bolts pass from the bottom edfie of the ONES-P1906 'of thebottom frame an up to the top face of the cylinder on ere E, these s tay-bolts will be of consider able length m lar r. engines, and as they are to be tightens at a tension exceeding the onetowhich they will be exposed in consequence of the piston ressure, they nail besubject, 'duringthis tig te'ning, to a m sidierable elon ation' requiring a considerable amount 0 work in tightening them an work, whenever it bechmesnecessary to remove the cover in order to inspect the eugine, each stay-bolt is fitted. with an extra nut R, Fig. 1. By means of this nut, the longer part of each stay-bolt is given the requisite tension, at the same timeas the It shaped beds become tightened to the bottom frame. This work has only to be performed once via, when the on no is fitted u tor the iirst time" When t e covers are .ing placed in position it will thenbnly be neces sary to produce e requisite tension in tin shorter portion of the stay-bolt, which "Gn the drawing, 'enemanner of construct-J in tlie invention is illustrated,

The cylinder covers E, which are she in such a manner that they meet one anot er at-the center lines between two cylinders,

are here 'oined together by means of the bolts L, ig. 2. In the lane of the joint the long connecting b0 ts" H through the covers and the latter are thereby e htened firmly against the A-shaped beds 3, which. are constructed inordinary ,manner, with the exception that they are i 1 hereextended clear up to the bottom face of the eaten.
